PURPOSE:To make the distribution of the temperature uniform at the surface to be joined, and to obtain the more excellent joining state. CONSTITUTION:On the case that the rear end part of the preceding slab and the top end part of the following slab are made in contact, at least, with both ends of lateral direction of each slab, and also the alternating magnetic field to penetrate to the wall thickness direction of these slab is impressed, and joined while enlarging the joining surface gradually by forcibly pressing while heating, the pressing force for satisfying the range of the changing speed of joining length 15-130mm/s over the sheet lateral direction of each joining range is impressed at the parts to be joined of the preceding slab and the following slab. |
